The height of any nested stack of chair frames 5105 is primarily a function of the thickness of crossbars 5130, chair back 5115, front legs 5120, and back legs 5125, as shown. The angle of rise of any nested stack of forty chair frames 5105 is also primarily a function of the thickness of crossbars 5130, chair back 5115, front legs 5120, and back legs 5125, as shown. Therefore, the angle of chair support structure 5830 must be set to support any nested stack of chair frames 5105 having certain dimensions in an approximately vertical position; i.e., when chair frames 5105 are redesigned with different dimensions, the chair support structure 5830 will also be changed. In the present example, the angle of chair support structure 5830 is approximately 32 degrees from vertical, as shown. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, such as user preference, advances in technology, intended use, etc., other arrangements, such as adjustable angle chair support structures, etc., may suffice.

Preferably, built-up welds 7205 comprise crossbar-plate welds 7225 between crossbars 5130 and crossbar plates 5135, as shown. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as advances in technology, user preference, aesthetic design, materials strength, etc., other reinforcements, such as additional crossbar plates, larger crossbar plates, a crossbar plate between the crossbars adjacent the seat back, using the seat back structure as reinforcement, etc., may suffice.

In use, modular furniture system 100 disclosed herein preferably permits rapid assembly and deployment as well as preferably permits rapid disassembly and retrieval. In the rental industry, set-up and tear-down times become critical. With only a few chairs, if these times were measurable in minutes, assembly and disassembly would not be taxing. However, in the rental industry, a single venue may need hundreds or thousands of chairs and in deployment and retrieval of these chairs trimming even a few seconds off each handling of a chair is advantageous. Modular furniture system 100 preferably utilizes various features (as disclosed herein, i.e. tool-free attachers, nested stacking, transporter system, etc.) to minimize the amount of time needed to deploy a chair from a stacked and disassembled state to a useable state as well as the amount of time needed to retrieve a deployed chair to a stacked and disassembled state. Additionally, modular furniture system 100 preferably still satisfies the needs of aesthetics, compact storage, durability, repairability, replacability, and changability, as the rental industry demands.
